Blue Whale

The largest mammal ever to grace the planet

The Blue Whale can measure 31 meters in length and weigh 100+ tons. Classified endangered there is an estimated only 12 to 20,000 remaining around the globe. The Perth Canyon is the Autumn feeding grounds of these incredible whales and one of the only locations in the world the elusive Blue Whale can be sighted in the wild.

This is your opportunity to be part of a new frontier of research and development with Whale Watch Western Australia as we continue to document, observe and identify these gargantuan and graceful creatures.

The Perth Canyon is a Biomass bonanza which stands unrivalled on the Western Australian coastline as the marine production epicentre.

The migration of the Blue Whale unfolds every year and is centred around finding krill. During the summer months the Blue Whales gather to feast on krill swarms in the Bonney Upwelling located off the southern coastline of Australia. Preparing for the long migration ahead the change of season as we shift into Autumn signals the arrival of Blue Whales in the Perth Canyon as hundreds gather to feed on the abundant krill and stay in the area for a few weeks.

The next stage of their journey during the winter months takes them north as they travel into international waters and make their arrival in the Banda Sea. Feeding continues here along with the birth of newborn calves as the females raise and nurture the next generation in the warm tropical waters. Spring observes the Blue Whales continuing back towards Australia where they will arrive back in the Bonney Upwelling just in time for the summer feeding season.

Located only 27 nautical mile off the Perth coastline

Boasting gargantuan dimensions larger than the Grand Canyon with origins dating back to the entrance of the Swan River in Perth, Western Australia. Research teams have monitored Blue Whales along with many other cetaceans and mega fauna that come here to feed on krill created by the Leeuwin Undercurrent and the Perth Canyon topography. This interaction creates nutrient rich upwelling waters where phytoplankton develops and an intense food chain for marine life prospers. This new Whale Watch frontier just off the Perth, Western Australian coastline is the feeding grounds for the largest known aggregation of Blue Whales in the southern hemisphere and our Perth Canyon Blue Whale tour is the only genuine, guaranteed Blue Whale tour of its kind in Australia.

The biodiversity includes Sperm Whales, Pilot Whales, rarely sighted Dolphin species, Australian Sea lions, Sharks, Migratory Sea Birds, Sunfish, Tuna and much more who gather to feed on this biomass bonanza which stands unrivalled on the Western Australian coastline as the marine production epicentre.

“It’s the major feature on the West Australian coastline and stands unrivalled in terms of marine life and productivity.” Professor Pattiaratchi – University of WA
